Awesome product - Competition Electronics Pocket Pro II Shot Timer

Yes, you can get a free shot timer on your cell phone that costs nothing. But;
1- The beep on this is really loud (if you want it to be since it's adjustable)
2- You can adjust the resonation so it won't pick up echos in a concrete range but can also adjust to catch super fast shot strings.
3- It's easily operated with gloves on since it has big buttons. Adjusting par time or reseting could be done with mittens on.
4- I sometimes practice inside with replica bb guns and obviously they're really quiet but you can adjust the sensitivity to pick up even those. Or, if you'r at a range with others shooting just down the way you can turn down the sensitivity so their shots are not picked up on your shot string.
5- You can even adjust how long the backlight stays on
6- With all these "adjustments" and even displaying time and date you'd think it might be complicated to work. Not the case, super user friendly and simple menu navigation.
7- And, finally I don't even remember if it's double or triple A batteries because this things lasts forever. I probably have 30 hours of actual use on it and I think it shows the battery at 1/3.

Longest review ever but this simple and durable little box is great buy!
